Answer:
x < −6
Step-by-step explanation:
In inequalities, the division by a negative number results in change of the sign. That is from less than to greater than and vice versa.
Therefore,
3x − 2 > 5x + 10.
= 3x - 5x > 2 +10
= -2x > 12
= x < -6
The sign changes as defined above.

Answer:
b = 3Vh
Step-by-step explanation:
When they ask to solve for b, you are essentially rearranging the equation so that b is alone on one side.
V = 1/3bh
(V)(3) = (1/3bh)(3)
3V = bh
(3V)/h = (bh)/h
3Vh = b
b = 3Vh
100-20 round the last numbers so they have a 0 at the end so 4 or under is 0 and 5 or higher is 10 so 100 - 20 is 80
